iPhone 7 iOS 13.5.1 Jailbreak
Developers have released an iOS 13 jailbreak tool that's compatible with iOS 13.5. That said, it isn't compatible with iOS 13.5.1.
The developers behind the "unc0ver" jailbreaking tool for iOS have released a new version, dubbed 5.0.0, that's compatible with iOS 13.5 and most versions of iOS that fall between iOS 13.5 and iOS 11.0. The jailbreak tool doesn't work with iOS 12.3-12.3.2 and iOS 12.4.2-12.4.5.
Apple's iOS 13.5.1 update patches up the exploit used to create the jailbreak. So if you want to jailbreak, you'll want to avoid iOS 13.5.1 for now.
